The invention provides a radio pneumatic braking system of a railway freight train and an intelligent control method, and belongs to the technical field of railway freight train control. The electric pneumatic brake control valve is arranged on the vehicle, the vehicle can control opening and closing of the first channel and the second channel of the two-channel electromagnetic valve based on the locomotive electric signal instruction, and brake and brake release are achieved. Compared with the prior art that braking control is achieved based on train pipe pressure changes through a 120 control valve, the electric pneumatic braking control valve is controlled based on the locomotive electric signals, all the vehicles can synchronously receive the locomotive electric signals and brake and relieve synchronously, braking waves are eliminated, and braking synchronization is achieved.
本发明提供一种铁路货物列车无线电空制动系统及智能控制方法,属于铁路货物列车控制技术领域。本发明通过在车辆上设置电空制动控制阀,车辆可基于机车电信号指令控制双通路电磁阀的第一通路、第二通路的开闭,实现制动和制动缓解。相对于现有技术中通过120控制阀基于列车管压力变化实现制动控制,本发明实施例基于机车电信号控制电空制动控制阀,各车辆可同步接收到机车电信号,并同步制动和缓解,消除了制动波,实现了制动同步。
